The RENFE Class 354 was a series of eight diesel hydraulic locomotives manufactured by Krauss-Maffei in Germany specifically to pull Talgo pendular coaches which were introduced shortly before the acquisition of these machines. The appearance and design is very similar to the RENFE Class 353, but with improvements; specifically in terms of installed power. ==Background and design== Delivered between 1983 and 1984, these engines provide a total power of , a figure never before reached by any other Spanish locomoitive〔The RENFE Class 340 (also a twin engine/transmission Krauss-Maffei machine) with was nearly as powerful.〕 The units have two cabins, like the predecessor Class 353, the twin engined / twin hydraulic transmission design from Krauss-Maffei can be traced back in Spain to the single cabined RENFE Class 352 and the RENFE Class 340, and further back to the DB Class V 200 of the Deutsche Bundesbahn. The locomotives represent a steadily increasing requirement for engine power, from the Class 352, to the Class 353, and then to these engines, with over 800 hp more power. Such high power was needed to drag the new Talgo tilting trains, which thanks to their natural pendulation system can be used with higher lateral acceleration than conventional trains, passing through curves at up to 25% faster. With these locomotives a maximum speed of this train was originally . Later in July 1986 a simple change of gearing and the fitting of the 'ASFA 200' safety system enabled the maximum speed of these locomotives to be raised up to . The only other diesel locomotive in RENFE's fleet with a maximum speed of is the more recent diesel electric RENFE Class 334,〔as of 2009〕 however this locomotive has a lower engine power, further reduced by the requirement to provide an electrical supply for the carriages,〔The Class 354 has no auxiliary generator for train supply, auxiliary generators being provided in parts of the Talgo pendular units themselves.〕 giving it a disappointing acceleration performance in comparison.〔(Comparativa entre las locomotoras series 334, 354, y 333-400 de Renfe ) Comparison of RENFE locomotives of class 334, 333.4 and 354.

Later they received the ''Grandes Lineas'' livery, also based on white and blue, (in July 1998 ''354-003'' was the first to receive it). In 2004 the logo 'Talgo' was removed from the sides of the locomotives - a minor change. The class later received improvements such as sound-proofing of the cabin and air conditioning equipment (fitted on the roof). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「RENFE Class 354」の詳細全文を読む スポンサード リンク
